Question

If two dice are rolled one time, find the probability of getting these results. Rounded to 3 decimals(d) A sum greater than or equal to 8P( sum greater than or equal to 8)=

Answer 1

Given data:

Two dice rolled together.

The events when sum is is greater than or equal to 8 are,

$\lbrace(2,6),\text{ (3,5), (3,6), (4, 4), (4,5),(4,6), (5,3),(5,4),(5,5),(5,6),(6,2),(6,3),(6,4),(6,5),(6,6)}\}$

The expression for the probability when sum is greater than or equal to 8 is,

$\begin{gathered} P(x\ge8)=\frac{15}{36} \\ =\frac{5}{12} \end{gathered}$

Thus, the probability when sum is greater than or equal to 8 is 5/12.
